Artificial Precession and Instability in Solar System and Planetary Simulations: Analytic and Numerical Results

open access: yesThe Astrophysical Journal
Wisdom–Holman (WH) methods are algorithms used as a basis for a wide range of codes used to solve problems in solar system and planetary dynamics. The problems range from the growth and migration of planets to the stability of the solar system.

Evolution of small bodies in the solar system

open access: yesJapanese Magazine of Mineralogical and Petrological Sciences, 2005
Orbital evolutions and spectral changes of small bodies in the solar system are discussed. Recent discovery of Kuiper belt objects changed the image of our solar system. The size of the largest body is close to that of Pluto. Orbital stability and simulation studies clarified a route from Kuiper belt objects to short period comets through Jupiter ...

Asymmetric Lamellar Templating of the Perovskite/C60 Interface for Scalable Inverted Perovskite Photovoltaics

open access: yesAdvanced Materials, EarlyView.
Asymmetric lamellar templating at the perovskite/C60 interface is achieved using a laterally polarized indole spacer. Surface anchoring and Ind–Ind assembly form a π‐rich lamellar interphase that supports uniform C60 contact formation, suppresses recombination, preserves electron extraction, and enables certified high‐efficiency cells and modules with ...

TEST OF A SOLAR-HYBRID MICROTURBINE SYSTEM AND EVALUATION OF STORAGE DEPLOYMENT [PDF]

open access: yes, 2010
A solar-hybrid microturbine system using a tube receiver and a Turbec T100 was tested at the Plataforma Solar de Almería. The design receiver outlet temperature of 800°C was achieved with an open receiver aperture and also using a pressureless quartz ...

Autonomous Folding of Soft Matter From Living Polymers

open access: yesAdvanced Materials, EarlyView.
Origami structures are endowed with “living” polymer creases that grow, remodel, and stiffen in response to nutrient solutions. This post‐fabrication growth enables autonomous folding, iterative regrowth, and mechanical tuning involving origami assemblies, such as cranes, Miura‐ori tessellations, rigid and non‐rigid square‐twist patterns, establishing ...
